Raleigh ratio

The dimensions of Raleigh ratio are cm-1. It is common to measure scattering at an angle of 90° and hence,... 

And the Raleigh ratio for a solution containing N scattering centers per unit volume is given by (15) ... 

Eq. (3.45), then the slopes dS /dq and d5 /dcm of the two lines at the origin would give i g/3 and 2A2] the limiting value S q = 0, Cm = 0) would furnish N. Actually, in experiments directly measurable quantities such as the Raleigh ratio E and the weight concentration are usually employed, rather than S and Cm- Corresponding substitutions can be carried out in Eq. (3.45) which is then converted to... 

The scattering intensity expressed as the Raleigh ratio R(q) is assumed to be due to thermal concentration fluctuations (ergodic contribution) and to... 

Theoretical aspects of emulsion formation in porous media were addressed by Raghavan and Marsden (51-53). They considered the stability of immiscible liquids in porous media under the action of viscous and surface forces and concluded that interfacial tension and viscosity ratio of the immiscible liquids played a dominant role in the emulsification of these liquids in porous media. A mechanism was proposed whereby the disruption of the bulk interface between the two liquids led to the initial formation of the dispersed phase. The analysis is based on the classical Raleigh-Taylor and Kelvin-Helmholz instabilities. 

At ratios of 5 (r/A) reflection and refraction dominate and give optimum sensitivity at lower values the less effective Raleigh and Mie processes dominate, while at larger values the response declines as the surface area to volume ratio of the droplet decreases. 

The correlation between the Raleigh reflectivity coefficient, R, and the impedance ratio is...
